We are beginning Phase 4 construction in June 2023, the last phase of construction on the Hallwood Side Channel and Floodplain Restoration Project. During this phase, we will remove the final portion of the middle training wall, complete final grading of Phase 3 and 4 floodplains and tertiary channels, plant additional trees, and place [...]
Phase 1 was implemented in 2019–2020 and created an enhanced 89 acres of historic floodplain habitat, 1.7 miles of perennial channels, and 3.7 miles of seasonal channels. Over the course of 2021, biological monitors
In November 2021, Phase 2 of the project was completed with approximately 800,000 cubic yards of rock having been removed from the Middle Training Wall. This phase restored an additional 34 acres of historic floodplain habitat and 1.6 miles of perennial side channels for the benefit of Chinook salmon, steelhead, lamprey, sturgeon, and a diversity [...]
Just a few months after Phase 1 of the Hallwood Floodplain and Side Channel Restoration Project was completed, juvenile Chinook salmon and O. mykiss (rainbow trout/steelhead) were documented utilizing the newly constructed side channels! Watch them in the videos below, captured by Cramer Fish Sciences biologist Philip Colombano. https://www.hallwoodproject.org/wp-content/uploads/2021/06/HW_Vid_2_CHN.mp4https://www.hallwoodproject.org/wp-content/uploads/2021/06/HW_Vid_8_OMY.mp4Schools of juvenile Chinook salmon (left) and [...]
Construction activities for Phase 2 began in early April 2021. This year the team will enhance another 34 acres of floodplain and 1.6 miles of seasonal side channel to provide habitat for juvenile rearing Chinook salmon and steelhead. We will also plant about 38 acres of riparian vegetation both in the Phase 1 footprint completed [...]
The project team finished construction of Phase 1 in fall 2020. Approximately 1.2 million cubic yards of sediment was removed to expose historic floodplain habitat for Chinook salmon, steelhead, and sturgeon. Miles of seasonal and perennial side channel habitats were carefully engineered to provide additional rearing habitat for native fish. Since completion, Chinook salmon and [...]

We are pleased to announce that the Hallwood Side Channel and Floodplain Restoration Project has resumed! A Time Variance Request was approved by the Central Valley Flood Protection Board (CVFPB), which grants the project an opportunity to start early while flows are low enough to allow access. Phase 1B began with the installation of the [...]
Safety is our primary concern for all who work on this project and the greater community. In compliance with CDC guidelines, the Project Team including Teichert and all environmental consultant staff, will implement the following protocols to prevent the spread of COVID-19. Frequent hand washing. At a minimum, before starting work and after touching one’s [...]
Progress as of late September 2019. Standing on the middle training wall looking west toward the Sutter Buttes. Front loaders are progressing through the area to remove gravel and cobble to increase lateral connectivity on the Lower Yuba River.
